I am having some concerns with my Arduino Uno. This my first one, and I bought it for a school project. I set everything up, and plugged it in to start the process of transferring the code. I plugged it in to see two lights going a green power light, and a yellow light that was not flashing next to pin 13. At first our drivers of the COM and the LPT were not there, so we re-downloaded the IPE program. Then they showed up. The driver of the Arduino still not showing up. I have read and fallowed the troubleshooting guide to the extent that I could. But it didn't work. I even went to the extent of purchasing and trying another wire thinking that would help. But nothing has worked.
